Every kde app that is not part of the main package (koffice,kopete,etc..) installs in /usr instead of /usr/kde... So it recreates the kde directory structure (apps,share,config under /usr/share for this apps. I think this has to be the messiest setup and can't believe this is intentional. For every changes I need to make ( a lot) I have to figure out if it came as part of kde main or not then go dig it out. If this is intentional!!!! is there a way to change this?
isn't a bug
Detailed answer: Yes, this is intentional. You're welcome to suggest a better alternative. If the KDEs aren't in /usr/kde/<version>, you can't install more than one version side by side. If 3rd party kde apps go into a KDE dir (somethere under /usr/kde) then 1) once you install a newer KDE and uninstall that one, they're not in the path anymore 2) if you add them to the path, you're also adding that KDE version to the path, and if you then run another KDE version you get into big trouble and 3) the install location is not determinstic. Therefore they live in /usr, which is also where all other non-kde-base apps live, conforming to the FHS.
